The term was coined by the late psychologist Jerome Singer, who was dubbed the “father of daydreaming.” From his research, Singer broke daydreaming into three categories:
Positive constructive daydreaming, which features playful, wishful images and planning
Guilty-dysphoric daydreaming, which is characterized by obsessive and anguished fantasies
Poor attentional control, which is trouble focusing on an ongoing thought or a task you’re supposed to be doing (i.e. the kind of daydreaming that typically gets a bad rap)
“Positive constructive daydreaming is associated with a broad array of positive constructs, including creativity, planning, problem-solving, memory consolidation, and self-reflection,” says Stella Panos, PhD, a neuropsychologist and director of neuropsychology for the Pacific Neuroscience Institute in Santa Monica, California. “This is different than other types of mind-wandering that do not seem to have a beneficial impact.”
